JOHN F. KELLY, OF PITTSFIELD, MASSACHUSETTS.

MACHINE FOR PERFORATING MUSIG-SHEETS.

Specification of Letters Patent.

Application filed April 1 3, 1911.

Patented June a, 1912. Serial No. 620,735.

To all whom z't may concern: 1

it known thatl, JOHN F. KELLY, a citizen of the Unit-ed Statesof America, re-

.siding at Pittsfield, in the county of Berkshire and State of Massachusetts, have invented new and useful Improvements in Machines for Perforating Music-Sheets, of which the following is a specification.

My invention relates to improvements in perforating machines. and is designed more particularly as an electrical machine for cutting or perforating av metallic music roll which is then used as an enlarged pattern for the playing rolls of self-playing musical instruments.

The machine is designed for perforating a metallic sheetwith holes of theproper length and size, and spaced from each other the desired distance. The invention consists, in general, of a table or carriage that is movable right and left transversely to the line of movement of the roll to he cut and is provided with a series of graduated punches that operate transversely to the line of movement of the metal sheetto he perforated, and a die thereon with which-the punches register.

The machine is provided with a note scale representing the notes of a piano and the markings for controlling the expression, over which 'moves a pointer or, index to which a contact brush is attached for controlling the electrical circuits; and a second pointer, the brushof which establishes electrical connections through suitable magnetic clutches whereby the table is automatically operated through a predetermined transverse distance when it will come to rest by the circuit being opened. In this position of the table the punching operation takes place in the roll, suitable means being provided for advancing the roll to he cut.

The details of construction and operation of my invention will be fully set forth in the specification and drawings forming av part thereof, and specifically pointed out in the claims. 1

Referring to the drawings,Figur e 1- is a front'elevationof the machine showing the reciprocating table, the clutch mechanism for connecting and disconnecting the source of power by means of which the table is transversely operated, and the index mcch aiiism which determines the number of punches to be operated for making a cut ting to represent. any particular note. Fig. 2 is a transverse sectioned view on the line 2-2 of Figl 1 showing the rack and pinion construction for. transversely moving the table in opposite directions, the hand operated ratchet device for advancing the metal:

ribbon forward in a step oy-step manner, graduated punches, and the clutch for releasing the operating shaft when the punching operation is to be performed. Fig. 3 is a diagrammatic view showing the electrical connections of the machine.

Referring to the drawings in detaiha designates the transversely reciprocating table which carries the die b and the set of graduated punches c. The tables moves lengthwise of the machine and at right an gles to the line of motion of the metal roll to he perforated and is provided with a rack (Z at its lower edge with which meshes a gear 6, which gear is adapted to be driven in opposite directions by means of two beveled pinions f and that are mounted on ashaft h and which are operated by means of the magnetic clutches 2' and 7', The direction of rotation of the gear 6 by means of the pinions f and 5/ depends upon the energization of either one or the other of the clutches or The wires in and m supply" the current to the clutches i and j, and said wires are connected to the two branch terminals 0 and 79 that are insulated from each other by means of the pie e of insulation o These branch terminals 0 and y) 'may he placed in electrical connection with the main wire 9 by means of the brush 9 that slides on them, and they are electrically connectedto the brush a which engages the main wire 1 that is connected to the source of electrical energy to.

Attached to the brushes 1" and s is the pointer twhich moves over the note scale a.

Wire is or m to the magnetic clutches 2 or 7' energizing that partlcular clutch so as to shift either one of the pinions f or 9 into mesh with the gear e-causingthe table a to 5 move, for instance, toward the right, it the current flows from the terminal t0 the clutch 2'.

In order to perforate or cut an opening in the metal roll of the correct length, an index device is shown at 9 provided with figures which indicate and fix the number of punches which are to be brought 'into action to cut the roll.

The index device raises and lowers the stepped punch selector .2 which is adapted to engage the rack 3 which, in turn, operates the pinion tthat engages the punchingrod 5 that carries the set of mraduated punches 0.

2e 6 designates an operating shaft that is provided with a worm 7 and with which the teeth of the gear 8 engage. The gear 8 is thrown into and out of action by means of the clutch 9 which isopcrated by means of the releasing magnet 10 so that when the clutch or pin 9 is retracted, the spring- 11 will throw the gear 8 into operation to effect the punching of the metal ribbon, power being transmitted to the gear 8 and shaft 6 by means of the belt 8 The gear 8 is connected to the stepped punch selector 2 by means of the link 12, whereby motion is' transmitted from the shaft (5 to the punchrod 5.

It should be observed that the branch terminals 0 and p are mounted on a rack 13 which moves withthe table (I, and this rack engages with the pinion 14 on the same shaft of which is secured a pinion 15 that engages the rack 10 of thetahle a. This system of gearing determines the correct ratio between the width of the meal roll that is to be punched'and the note scale u for the ordinary eightv-eight note piano.

When the operator wishes to punch any particular note, he slides the brush 8 and index pointer t to the particular note that appears on the piece otmusie that 'is'tobe reproduced or punched in the niastcrroll. This causes the brush r to engage, say the righthand terminal- 0, and establishes an electrical connection with the main wire {7 through the brushes 8 and '2'" to therigh thand clutch. 2' which throws the pinirn g into mesh with the gear 6- which move; the table (1 toward the-1 ght. Movement ii this direction will continue until the carriage pointer 17 moves the piece of insulation 0 into engagementwilh the brush 7*, thus opening the circuit to the clutch v1 and stopping the movement of the table.

lie to re the punching otthe shoot is perliormed, u is that the exact pl. n ion at the iahlc nuinatr positioning and the punches carried tl'iereby which has just been described is not always its exact position with relation to the note scale, and in order to bring the table a into the exact position and. prevent a n v back lash, its lower edge is provided with teeth 18 with which the teeth 19' on the red. 19 mesh. The distance between two oi these teeth is equal to the spacing of one note from the other on the note scale.

If the preliminary positioning is *ithin half the width of two teeth the locking action must insure precise adjustment of the punches. g

The engagement of the teeth 1.8 with these on the rod 19" is effected b vaneans oi. an electromagnet 2 The path of the current when "the in its preliminary p sition r electromagnet 20 ei-mrgizcc From the source to to t-h" contact piece 25 and. its switch to .llfl wire 26,

litter the table has come to restreason of the circuit to the clutch 2' being opened when the brush r engages the piece of 1nsu-' device 27, wire The armature 3301" the eleetromagnet is 2- attrae'tedand causes the teeth of the rod 10 to mesh with the teeth the table, which arn'iature is held in r attracted position during; the punrhii'igr operationand in order to maintain this attracted position of the armature, current [lows from 'w to the crmtimt-liar wire Set, to the mal-re and break device 35 (which is closed after the make and break device 27 is opened) permitlingthe current to flow 36 to the wire 37 through the electron'iagrnet, 20 and common return 32 back to the. other terminal of the source ct energy tr. it being of course understood that the contacts 27 are not opened until after 35 is closed.

After the; punching operationythemetal roll (which is shown 1n Fig. 2 at 46) is fed forward by means of the hand -.operated- 2 ratchet lever 47,- the teeth'of which. engage the ratchet wheel 48 and cause the ribbon 46 to move forward the desiredspace corresponding with the time of the music-that is being copied, when the operations just delscribed are repeated. The note index If is set to eiiect the cutting of another note.

It will be seen that I have produced a per-- forating :nachine'for making master rolls that is extremely accurate in 1ts cuttings of {the notes, and one that maybe operated at considerable speed.
